Abstract: The present study was aimed to examine the phytochemical constituents present in the tuber of P. rotundifolius. The GC-MS analysis determined the presence of forty different phytochemical compounds in methanolic extract of tuber of P. rotundifolius. Based on percentage of area, Cis-Vaccenic acid was identified as an active phyto component. FT-IR results proved the presence of Alcohols, Phenols, Amines, alkanes, aldehydes, carboxylic acid, iso cyanides, alkyne, isocyanate, ketones, aromatics, phenols, tertiary and primary alcohols and Chloro compounds which shows major peaks at 3966.15, 3769.76, 3394.56, 2947.66, 2835.85, 2524.80, 2362.84, 2214.45, 2043.33, 1656.15, 1451.82, 1413.08, 1112.70, 1024.79 and 668.99 respectively. The result of the present study help to enhance the usage of P. rotundifolius for its medicinal uses which is greatly depends on the diversified chemical substances present in the tuber of P. rotundifolius.
